Yes, I also realized that showing the category page by default might provide better orientation for new users and changed my homepage.
When read @HAWK’s statement, I’m wondering: if that is indeed a general “rule”, then wouldn’t it make sense to set the category page as default homepage for new forums?
Disclaimer: I’m assuming that there is a default homepage. I don’t remember whether this is something you are asked to specific in the setup process, but even if it is, there’ d seem to be something that pushed me towards choosing “Latest” as my homepage. (As a side note: it is also somewhat difficult to find how to change the homepage)
